BRAKE MECHANISM.

1 To all whom it may concern:

Be it known that I, PETER S. Mon, a citizen of the United States,residing at Creston, in the county of Lincoln and State of Vashington,have invented new and useful Improvements in Brake Mechanism, of whichthe following is a specification.

An object of the invention is to provide a brake mechanism, particularlyadaptable for use on agricultural vehicles and the like, provided withrudder wheels, the brake be ing operable on the rudder wheels to retardthe movement of the vehicle.

To accomplish the desired result, use is made of a brake shoe hingedlymounted on the frame of the vehicle and adapted for engagement with thecaster wheel thereof, relatively adjustable rods having their inner endsconnected, an actuating lever hingedly mounted on the frame of thevehicle and connected with the outer end of one of the said rods, theouter end of the other rod being connected with the said brake shoe anda notched bar mounted on the frame of the vehicle and adapted to beengaged by the said lever for adjustably positioning the said brake shoerelatively to the caster wheel.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which Figure 1 is a sideelevation of my device showing the same applied to the rudder wheel ofan agricultural vehicle, the brake shoe being in engagement with therudder wheel. Fig. 2 is a vertical sectional view showing the brake shoedisengaged from the rudder wheel. Fig. 3 is a rear elevation. Fig. 4 isan enlarged perspective view of the scraper.

Referring more particularly to the views I provide a vehicle frame 10having secured thereto a plurality of bearing lugs 11 and mounted toturn therein in a wheel rod 12 secured to a frame 13 having revolublymounted thereon a caster wheel 14, the upper end of the wheel rod 12having secured thereto a tiller 15 for guiding the caster wheel 14. Theframe 13 is provided with depending portions 16 on which the casterwheel 14 is mounted and pivotally mounted on the frame is a U-shaped bar17 having connected thereto an end of a rod 18. The other end of the rod18 is looped to encircle Specification of Letters Patent.

Application filed May 16, 1911.

Patented Apr. 2, 1912. Serial No. 627,534.

a rod 19 also provided with a loop encircling the rod 18 and connectedto the said rods is a securing plate 20 for relatively securing the rodsin rigid position, an end of the rod 19 being pivotally connected to alever 21 pivotally mounted on a bearing 22 secured to the wheel rod 12by a set screw 23. Hingedly mounted at the rear end of the frame 13 is abrake shoe 24, the said brake shoe being adapted to engage the casterwheel l-fl in the groove thereof. Pivotally mounted on the U-shaped bar17 are rearwardly extending rods 25 having their outer ends threaded toreceive an aperti'lred plate 26 secured to the brake shoe 24. A notchedbar 27 has an end thereof secured to the tiller 15, the other end of thesaid bar being secured to the wheel rod 12 and the said bar is providedwith a series of notches 28 adapted to be engaged by an integral flangedportion 29 on the lever 21.

A screw 30 is secured to the lower end of the brake shoe 24 anddepending therefrom is a scraping plate 31, the said plate beingprovided with flanges 32 secured to the brake shoe 24. and a spring 33being positioned to encircle the screw 30 and act against the scraperplate 31.

In the operation of my device, when the brake shoe is disengaged fromthe caster wheel 14. and it is desired to apply the brake shoe the lever21. is moved upwardly, thus operating the rods to move the outer end ofthe U-shaped bar 17 upwardly and the rods 25 mounted on the bar 17 andconnected to the brake shoe 24; will be moved inwardly, thus pressingthe edge of the brake shoe into engagement with the caster wheel 14 sothat the rotat-ive movement thereof will be retarded. If it is desiredto retain the lever 21 in a particular position, the flange portion 29is permitted to repose in one of the notches 28 of the notched bar 27,thus rigidly positioning the various parts of my device. To release thebrake shoe from engagement with the caster wheel 14 the lever 21 ismoved downwardly, thus moving the outer end of the U-shaped bar 17downwardly and the resulting movement will disengage the brake shoe 24.from the caster wheel 1 1 as will be readily seen in referring to thefigures. The outer end of the scraper plate 31 is normally positioned toengage the caster wheel 14 and act as a means to scrape any accumulationfrom the groove of the caster wheel.

From the foregoing description it will be readily seen that an efficientand easily operative brake mechanism is provided and the same can bequickly manipulated by the person operating the agricultural vehicle sothat the relative speed of the vehicle can be at all times controlled bythe operator.

Having thus fully described the invention, what I claim as new, is

1. A brake mechanism comprising a U- shaped bar for pivotal engagementwith the frame of a vehicle, a rod connected to the said U-shaped bar, asecond rod engaging the first rod, means for rigidly securing the saidrods, a lever connected with the second rod, a notched bar mounted onthe vehicle and adapted to be engaged by the said lever, a brake shoehingedly mounted on the frame of the vehicle and extending between thesaid U-shaped bar, a plurality of threaded rods mounted to swing on thesaid U-shaped bar and a plate for adjustable engagement with the saidrods and secured to the said brake shoe, the said brake shoe beingadapted to engage or disengage the running gear of the vehicle when thesaid lever is operated.

2. In a brake mechanism the combination of a vehicle frame, a wheelrevolubly mounted on the said frame, a brake shoe hingedly mounted onthe frame and adapted for engagement with the said wheel, a U-shaped barpivotally mounted on the said frame, the said brake shoe being extendedbetween the sides of the said bar, an operating lever mounted on theframe of the said vehicle, a notched bar connected to the frame of thevehicle and adapted to be engaged by the said operating lever to rigidlyposition the same relatively to the notched bar and rods connecting thesaid operating lever with the said U-shaped bar for operating the saidbrake shoe when the said lever is operated.

In testimony whereof I afliX my signature in presence of two witnesses.
